Abstract: Se estudia el comportamiento de la estrella de mar de brazos múltiples (Coscinasterias tenuispina) ante la luz ultravioleta y luz blanca. Tras quince minutos de exposición a luz ultravioleta las estrellas reducen su actividad en comparación con los individuos sometidos a luz blanca, mostrando una clara tendencia a ocultarse. Además, estos animales cambian de color de forma notable y necesitan un mayor tiempo para recuperarlo una vez pasado el estímulo.
The behaviour of the fissiparous sea star (Coscinasterias tenuispina) when exposed to ultraviolet and white lights was studied. After fifteen minutes of ultraviolet light exposition, the sea stars reduced their movements (activity) when compared with individuals under white light, and showed a much clear tendency to hide. Furthermore, these animals remarkably changed their body colour and, after the stimuli disappeared, they needed long time to recover it again.
